A cop individualizing apparatus operates a circular conveyor of the type having a helical cop guide track on a vibratory basis by providing two unbalanced electromotors whose speed is controllably varied via a frequency converter alternating between two frequency stages as a function of the instantaneous cop supply requirement of an associated cop dispensing device fed by the individualizing apparatus, in order to assure advancement of the cops along the transport track of the circular conveyor in precise relation to the particular instantaneous cop requirement.

Cop individualizing apparatus

An apparatus removes textile articles such as empty tubes or full yarn packages from the individual posts on which such articles are supported simultaneous with advancing movement of the posts. The textile articles are removed in a direction generally parallel to the axis of the posts so that during removal detrimental binding of the textile article relative to the post does not occur. According to one aspect of the invention, at least one pair of endless belts are mounted in spaced, parallel relation to one another to form an elongate opening therebetween. The elongate opening is aligned with the travel path of the textile articles being advanced on the posts so that the textile articles automatically enter the elongate opening and are engaged by the endless belts without the need to stop or otherwise control the advancing movement of the textile articles. In another aspect of the invention, a pair of spaced, parallel elongate rollers are provided, the elongate rollers being rotated in opposite directions to effect removal of a textile article which has been advanced into the elongate opening formed between the rollers. The textile article removal apparatus preferably also includes a collection assembly for collecting removed textile articles in an orderly manner and an assembly for transporting loads of removed textile articles to a location for further handling.

A method for supplying winding units of an automatic winding machine with bobbins to be unwound from a bobbin feeding device, includes requesting a bobbin from the feeding device at a given winding unit, depositing a given bobbin requested by the given winding unit at a distance from other bobbins onto a conveyor belt running along the winding units, transporting the given bobbin to the given winding unit on the conveyor belt, subsequently removing the given bobbin from the conveyor belt and conducting the given bobbin to the given winding unit with a controllable bobbin removing device of the given winding unit, and preventing bobbin removing devices of winding units other than the given winding unit from diverting the given bobbin and from conducting the given bobbin to the winding units other than the given winding unit, and a device for carrying out the method.

A device for depositing and keeping a thread end in a cop tube of a spinning cop from a cop delivery point of a cop preparation station to a cop transporting device includes a pivotable chute with upper and lower ends disposed between the cop delivery point and the cop transporting device for receiving a spinning cop with a dragged-along thread end, a switchable suction device disposed at the lower end of the chute for supplying the cop tube with suction, and a device for tilting the chute from a vertical position to a horizontal position, the tilting device including a device for limiting acceleration and deceleration of the spinning cop in the chute during tilting.

A spool separating device for separating spool tubes with a relatively smaller diameter from finished wound spools with a relatively larger diameter, includes a vibratory conveyor with a bottom, an upper end, a sliding surface extended spirally upward along a given spool transport direction from the bottom to the upper end, a wall outwardly bordering the sliding surface, the wall having a slot formed at a given location therein, the slot having a height being greater than the diameter of a spool tube and smaller than the diameter of a finished wound spool and a length being greater than the length of a spool tube, an adjustable wall section in a position bordering the top of the slot determining the height of the slot, the adjustable wall section being resiliently moveable out of the position in the event of spool jamming, and an additional wall section determining the depth of the slot and approaching the bordering wall in the given spool transport direction for guiding the end of a spool tube of a spool which cannot fit completely through the slot back onto the sliding surface.
